The only thing I needed was to setup Multiviews in my Options in the hhttpd.conf file.

I had a problem because it was working with files with extensions like ".jpg" and ".gif" , but not with ".php". It was because my default conf files for Apache/2.0.40 (Red Hat Linux) was not including an Addtype line for Php, the PHP.conf files was working with a filter.

After this all is running fine for clear URLs without Rewriting rules.
